docker build时出现错误"debconf: unable to initialize frontend: Dialog"如何处理？

1. 详细日志如下:

debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend will not work on a dumb terminal, an emacs shell buffer, or without a controlling terminal.)
debconf: falling back to frontend: Readline
debconf: unable to initialize frontend: Readline
debconf: (This frontend requires a controlling tty.)
debconf: falling back to frontend: Teletype
dpkg-preconfigure: unable to re-open stdin:

2. 修复示例如下:

修改Dockerfile文件,

FROM ubuntu
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && \
       apt-get -y install sudo dialog apt-utils
RUN echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections
